Laser PWM und entsprechend.hal verändern

Hello PCW,

step by step im coming forward.
in the Hal Config by running the programm the laser_pwn_enable is turning on.

MANY MANY THX to you!!!

I was running the GCode from  FRankenlab and also the Laser_PWM_value is changing by the value in GCode Q150 or Q0,2
But i get no PWM Signal at the wirng to the laser.
I connected the Signal PWM wire to TB3 Pin3 and TB3 Pin 5 on the Mesa 7i76e

forum.linuxcnc.org/42-deutsch/44933-lase...aendern?start=0#none

What am i doing wrong?

EDIT
Found the Mistake. I havent hared the Ground from LAser Power Supply to MESA GND:
Now its working. Many Thx to you PCW!!!!!
 

I have one issue. If the Laser is in Idle Power 0 and i close Linuxcnc, the Laser goes Full power. Maybe the Mesa card switches. 

HOw is it possible to chance this?

This should be fixable with 2 changes

1. Use the opposite polarity output from the 7I76E card
2. Invert the PWM in the hal file:

setp hm2_7i76e.0.pwmgen.00.out0.invert_output true
